There are differing opinions but the two wallets mentioned above have had their share of security issues recently, not to mention 'coinbase' is not a wallet. Coinbase is an exchange platform where you can purchase/sell coins and leave them for trading purposes--but you do not have true possession of them, as you do not have possession of your private keys. The most secure wallets are hardware wallets--such as ledger nano-s or the trezor. Seeing as you are a newbie, perhaps a hardware wallet is not for you just yet. In that case, a software wallet such as electrum, coinomi or samourai are worthy options. Below we have posted links to our beginner guides on both wallets and exchanges so you can see the differences between the two and how they work together.
